Broadleaf Management w/o 2,4d

I heard a story yesterday of a "Master Gardener" that wrote a book recently. His solution for broadleaf weeds is to mow real short then let it grow out, repeat, and rinse
The broadleaf cannot survive the abuse of cutting that low (in his study or theory) however, the grass can. Eventually only the grass survives.
My initial thoughts are: May not work with dandelions, and if heat hits after a scalping - problems could occur.
What are your thoughts of this alternative to broadleaf chemicals?

Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage,,, I wonder what does...

Sounds like an experiment! Actually, that doesn't seem to make much sense if you consider that most weeds are weeds because they are so resilient. They are prolific propagators and/or they require little care. I.e. they will grow in compacted soils with little nutrients. I would doubt that most broadleaf weeds wood be killed off by such harsh treatment unless it was done for a long period of time in which case the grass would also suffer. Secondly, cutting the grass short allows dormant weed seeds on the soil surface access to light causing them to germinate making the whole discussion moot.

Competition is the idea; so just as, good turf crowds out weeds, this system supposedly gives grass the edge.
But yes, this is a call to experiment. I do have a patch of grass with weeds, because I never spray my own lawn.
However most of the weeds that survive in established turf are of the basal meristem variety and I don't see stopping them if they have enough root to survive. Then again - I have been surprised before.

For broadleaf weeds, you may want to try watering in some non-sulfured molasses. When it comes to these type of weeds, molasses is great because most broadleaf weeds need high nitrate levels. When you add molasses, you get bacteria, and some fungi growing, but mostly bacteria. These organisms take up nitrate and turn it into biomass, so the weeds will be less able to compete with the desired plant.

When you have sour grasses, like quack grass, crab grass, foxtail, nutgrass, goosegrass, johnsongrass and barnyard grass, those are a lack of a signal, a lack of the calcium signal. This is natures way of trying to regroup calcium and bring it to the topsoil. Try applying bonemeal to your soil to control these or I've found a fish hydrolysate by Schafer Organic Fish that contains 12% Ca. That's the most I've ever found with any fish product.http://www.schaferfish.com/fertilizer.html

Now if you have heathly turf, weeds won't be able to compete for space. But this just doesn't happen, you have to work at it. Weeds are indicators of what's missing in your soil, and actually work to draw what is missing from deep in the soil. So you need to pay attention to what weeds you have and what they are telling you.

I myself have used this technique...but timing is very important like you say...you need the rain.
